Macro Definition Documentation

BTN0_MODE

#define BTN0_MODE   GPIO_IN

Default button GPIO mode definition.

Since the GPIO of the button is pulled up with an external resistor, the mode for the GPIO pin has to be GPIO_IN.

Definition at line 46 of file board.h.

BTN0_PIN

#define BTN0_PIN   GPIO0

Default button GPIO pin definition.

Seeed Studio Xiao ESP32S3 boards have a BOOT button connected to GPIO0, which can be used as button during normal operation. Since the GPIO0 pin is pulled up, the button signal is inverted, i.e., pressing the button will give a low signal.
